Hi Frank I think as of today this is not possible. You could try and experience the "non-exlusive" feature of node-label which will officially come in 2.8 soon. Or you can try it in "Hadoop 3 alpha1" release too if its fine to check. YARN-3214 <https://issues.apache.org/jira/browse/YARN-3214> has the details for the nodelabel sharing concept.
